Description

Electronic device for communicating with external electronic device using USB connector

Technical Field

The present disclosure relates generally to electronic devices, and more particularly to electronic devices configured to communicate with external electronic devices using Universal Serial Bus (USB) connectors.

Background

In order to improve usability of electronic devices and meet various demands of users, electronic devices are being developed to provide more diversified functions.

In view of the development of electronic devices, data services are being developed in which electronic devices are connected to computers, external electronic devices, and the like through wired connections or interfaces so that data can be transmitted/received between these devices. The wired connector may be used to electrically connect a power source of the electronic device to the charger. The connector of the electronic device may be a USB-C type connector, which may be used to charge a wireless terminal of the electronic device or input/output data to/from the electronic device. The USB-C type connector may include a socket mounted on the electronic device and a plug connector to which wires are connected. The electronic device may transmit content to the external electronic device through the USB-C type connector, and when the electronic device is connected to the external electronic device through the USB-C type connector, these devices may be referred to as a host and a device. For example, when an electronic device is connected to a television through a USB-C type connector, the electronic device may be designated as a host (e.g., master device) and the television may be designated as a device (e.g., slave device). When the electronic device is connected to an external electronic device through the USB-C type connector, the electronic device may transmit data to the external electronic device, but the external electronic device cannot transmit data to the electronic device.

For example, when the electronic device is connected to the television through the USB-C type connector, the electronic device may transmit a display screen image to the television so that the television may display the display screen image, but the television cannot transmit a user input (or command) for controlling the display screen image to the electronic device.

Accordingly, there is a need for a capability to transmit user input to an electronic device such that a user viewing a display screen image of the electronic device through an external electronic device can control the display screen image displayed on the external electronic device, thereby allowing the user to control the electronic device through the external electronic device.

The arrangement order of the 12 pins formed on the upper surface may be the same as the arrangement order of the 12 pins formed on the lower surface, so that the connector 750 of the first external electronic device 102 may be inserted in an arbitrary direction. This structure allows a user to insert a cable of the external electronic device 102 into the connector 710b of the electronic device 101 when the cable is rotated 180 °.

The arrangement of the pins formed on the upper and lower surfaces of the contact substrate 705 is given in table 1 below:

TABLE 1

The USB-C type has 24 pins formed thereon, and due to reversibility, the 24 pins may be arranged in a mirror configuration. This configuration allows the user to rotate the connector 750 of the first external electronic device 102 180 ° and mount it on the connector 710b of the electronic device 101. For example, when Tx1+ and Tx1-are used, tx2+, tx2-, tx2+ and RX 2-may not be used; and when RX1+ and RX 1-are used, RX2+, RX2-, TX2+ and TX 2-may not be used. In this way, a conductive intermediate plate is included in the contact substrate 705 of the connector 710 b. In addition, there are 24 pins (e.g., 12 upper surfaces, 12 lower surfaces) in total on the contact substrate 705, but the corresponding pins may not be used at the same time. The pins to be used may be determined according to the connected cable, the connector attached to one end of the cable, and the connection to the connector 705 of the electronic device 101.

For example, when the upper surface of the connector 750 of the external electronic device 102 is inserted into the connector 710b of the electronic device 101 and faces upward such that the CC1 pin 710-5 of the electronic device 101 is connected to the CC pin 730-5 of the first external electronic device 102, the CC2 pin 720-5 of the electronic device 101 may be used to provide a power supply VCONN for identifying the IC of the first external electronic device 102. Further, when the upper surface of the connector 750 of the first external electronic device 102 is inserted into the connector 720b of the electronic device 101 and faces downward such that the CC2 pin 710-5 of the electronic device 101 is connected to the CC pin 730-5 of the first external electronic device 102, the CC1 pin 710-5 of the electronic device 101 may be used to provide a power supply VCONN for identifying the IC of the first external electronic device 102. The CC pins 710-5 and 720-5 of the electronic device 101 may be connected to the CC or VCONN of the first external electronic device 102, and the CC pins 710-5 and 720-5 of the electronic device 101 may support the CC and VCONN.

Referring to fig. 8, the electronic device 101 may perform BMC communication with the first external electronic device 102 in such a manner that clock and data are included in a single transmission line. Clock frequency 810 is twice the data signal frequency 820. All bits of data can be represented in two logical states. Each logical 1 of the inputs may be output as two different bits (10 or 01) depending on the previous value. Similarly, when a logic 0 is input, two identical bits (00 or 11) may be output. When the bit value of the encoded signal 830 changes from 1 to 0 or from 0 to 1, the value of the data signal 820 is 1, and when the bit value of the encoded signal 830 does not change, the value of the data signal 820 is 0. Furthermore, if bits 1 or 0 occur consecutively, an asynchronous problem may occur, but the BMC communication provides at least one zero crossing point within the two-bit data, so that the asynchronous problem of the serial communication can be avoided.

The first external electronic device 102 may send data to the electronic device 101 using a CC pin of the USB-C type. The electronic device 101 may notify the first external electronic device 102 that data transmission through a specific pin is possible, and may establish a communication channel with the external electronic device 102. The electronic device 101 may establish a communication channel with the first external electronic device 102 based on a CC pin of the USB-C type. After determining the communication method with the first external electronic device 102, the electronic device 101 may send content to the first external electronic device 102. Alternatively, the electronic device 101 may notify the first external electronic device 102 that data transmission through a specific pin is possible, and may transmit the content to the first external electronic device 102. The electronic device 101 may send content to the first external electronic device 102 using a TX pin of the USB-C type. The content may include a screen image currently displayed on the display 160 of the electronic device 101. Alternatively, the content may include data such as images and pictures stored in the memory 130 of the electronic device 101.

Steps 911, 912, 913, and 914 correspond to BMC communication step 910. During the BMC communication step 910, the electronic device 101 may acquire at least one piece of information selected from the identifier, power information, and information for determining a communication method of the external electronic device 102 from the external electronic device 102 using a CC pin of the USB-C type. In addition, the electronic device 101 may notify the first external electronic device 102 that the first external electronic device 102 may transmit data using the CC pin of USB-C.

In step 921, the first external electronic device 102 using the processor 610 may determine whether user input is received. The first external electronic device 102 may receive content from the electronic device 101.
